Abstract

Abstract: CeO₂nanotubes were synthesized by hydrothermal method using PEO-PPO-PEO (P123) as surfactant.The effects of reaction time, reaction temperature and concentration ofsurfactant on the formation of CeO₂ nanotubes were investigated. Themicrostructures of the samples were characterized by transmission electron microscope,X-ray diffraction and N₂ adsorption-desorption methods. The catalyticproperties of CeO₂ samples on methylene blue were also examined. Theresults indicate that single crystal CeO₂ nanotubes are obtainedwhen reaction time is 72 h, reaction temperature is 160℃ and molar ratio of P123 to CeCl₃·7H₂O is 1:5. Theexternal diameter of CeO₂ nanotubes is 40-60 nm, theirinternal diameter is about 20 nm and their length is 500-1000 nm. Theformation mechanism of CeO₂ nanotubes is subjected to dissolution-recrystallization,anisotropic growth and self crimping of Ce(OH)₃ crystal seed.Compared with CeO₂ nanoparticles and nanorods, CeO₂nanotubes demonstrate better catalytic activity on methylene blue, which isattributed to the remarkable adsorption of pore, exposure of higher activesurface (110) and considerable defects on the surface of CeO₂nanotubes.

Key words: hydrothermal, CeO₂ nanotube, catalysis
